506 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



slender shrub growing in forest. The outside was plastered all over 

 with thin, papery pieces of decaying leaves, white in color, or nearly 

 so, making the exterior very light-colored and conspicuous. Some of 

 these leaves hung down untidily, draping around the supporting stem. 

 There was also a fragment of snake skin in the outer layer of the 

 nest. The middle layer of nest material was of light-colored plant 

 material, with a lining of black fibers that contrasted sharply with the 

 white exterior. The nest was 75 mm. high (not including the loose, 

 dangling tail), with the interior cup 70 mm. in diameter, 40 mm. wide 

 and 30 mm. deep. The single egg (probably the set was incomplete) 

 was white, with a yellowish tinge (like old parchment), with a scarcely 

 perceptible wreath of a faint rufous tone. It measured 19.1 X 14.7 

 mm. Two days later the nest was empty." 



In preparing specimens, the relatively large size of the eyes was 

 obvious, as they projected laterally considerably beyond the side of 

 the cranium. In one, the width of the skull with the skin removed 

 was 14 mm, with the transverse diameter 10 mm. 



The species, divided into numerous subspecies, ranges from south- 

 ern Mexico through Central America and South America to Para- 

 guay, and Misiones in northeastern Argentina.
